NEVER BEFORE HAS ONE PRODUCT DONE SO MANY THINGS!
From the “DIY” home handyman, to the professionally-trained industry technician, LLFA® is an essential commodity in any repairman’s toolbox! It is an extremely versatile product with many different uses and functionalities. The strength of LLFA® makes it both a competent insulation solution and an invaluable puncture repair product. A punctured hose or pipe tightly wrapped with LLFA® Tape will immediately withstand internal pressure because the fusing action takes place so quickly. It can stop nasty leaks without having to turn off the water source. LLFA® Tape is strong (tensile) and flexible. These two characteristics are valuable for creating a long term solution which helps ensure additional repair is not required. Even after a 20 year lab aging test, LLFA® Tape remains strong.

LLFA® Tape used to seal a STEAM LEAK on a low pressure steam drain line at Nuclear Power Plant
After GTG® provided electronic information, verbal information and installation instructions, the Nuclear Power Plant personnel successfully sealed the above steam line leak. Below is an excerpted email from the Power Plant. “We spoke a few months ago regarding the use of your product here on site. With your help, we were able to get it approved and today we installed the tape on a steam leak on a low pressure steam drain line per the guidance you had sent us. So far this is looking good and we will continue to monitor it for the next several days. I have attached some before and after pics for you. Thanks for spending the time with me a few months ago and for your time with our Engineer.”

Turbine Oil Leak Repair, with LLFA® Tape, made by JEA Northside Generating Station in Florida, USA
During an LLFA® Tape demonstration, performed by GTG® Engineering, Inc. at JEA, Northside Station, a request was made to repair a turbine oil leak. The leak was at the interface of a smaller diameter externally threaded pipe into a larger diameter internally (female) threaded pipe that was associated with a Primary Air Fan for a 310 Megawatt, circulating Fluidized Bed boiler. The bearing is a Sleevoil Pillow Block Bearing. The leak was sealed using LLFA® Smooth around the dimensional change and 2″ wide LLFA® Tape over the entire connection. The JEA Manager Electric Production Maintenance stated that the repair would have cost $17,000.00 due to the fact that in order to make a full repair, the unit would have to be derated since they would have lost half the generating capacity of the unit for the length of the repair. On JEA performed a repair, themselves, using LLFA® Tape and LLFA® Smooth in which the leak was coming from a flat plate where the pipe fitting entered the plate. . There was oil leaking from the flat plate at the fitting. GTG® normally recommends that LLFA® Tape must extend a minimum of 1 to 1.5″ beyond the leak in order to make an effective seal; however, JEA used a combination of LLFA® Tape and LLFA® Smooth to create a “tadpole gasket” which was able to seal against a flat plate. I think we can safely say 1.25 to 1.5 gallons of oil in a 24 hour period. Below is an excerpt of the e-mail from JEA. “. I came up with a solution for that (sealing a leak against a flat plate) using your product (LLFA®). I cut a thin piece of smooth, rolled it into a thin cylinder shape and then wrapped it around one side of tape. Similar to a tadpole gasket. I applied it pressing the smooth to the flat plate. The theory being that the compression of the tape would press the encapsulated smooth against the plate, creating a seal. Looks like it worked. Impressed so far.” On JEA Northside performed another “tadpole gasket” style repair, using LLFA® Tape and LLFA® Smooth. Below is an excerpt of the e-mail from JEA. “Hope all is well with you. These pictures show another oil leak that we wrapped. It is on a bearing similar to the one you guys (GTG®) did for me. The difference being that this bearing is larger and was actually leaking about twice as bad, 2.5 + gallons every 24 hours. This is taken 48 hours after wrapping and shows no sign of any leakage. This stuff is good. Thanks “

LLFA® Tape Used for Sealing a City Gas Line Leak!
As we all know, access to clean water as well as properly maintained gas are basic necessities, but it is a huge task to keep all of the systems and infrastructure working. Without these, there are obvious implications, such as low access to potable water and higher incidences of water-related diseases. Access to a suitable water source does not necessarily mean access to clean water. Pipes can be rusted, corroded and contaminated, which can also create dangerous leaks in gas lines. So in a country as heavily populated as China, maintaining proper city infrastructure can present a huge challenge. On April 2nd 2018, a port in southwest China’s gas company used our products, LLFA® Smooth, LLFA® Tape and LLFA® Garde, to seal the city’s main gas line. It had been corroded and had an operating pressure of 7 kg. For this task, the construction crew used LLFA® Smooth to fill in the corroded areas for extra leak blockage, followed by the 2 inch-wide LLFA® compression tape. They also used our LLFA® tensor tool in order to pull the tape to it’s maximum tension for the most effective results. The finished repair was further protected by our LLFA® Garde. In total, sealing this major leak on a main city gas line took 40 minutes to complete with effective results. Thanks to all the diligent city workers who help keep our water and gas lines free of leaks and corrosion!
